2. Generic Parameters

Here in our network configuration, we need to pass the "GIT PROXY" configuration.

• If you do not need, remove the --build-arg NEEDED_GIT_PROXY=".." option.
• If you do need it, change with your proxy value.

3. Build AMF Image

               --build-arg NEEDED_GIT_PROXY="http://proxy.eurecom.fr:8080" \
               component/oai-amf
$ docker image prune --force
$ docker image ls
oai-amf                 production             f478bafd7a06        1 minute ago          258MB
